FALL RIVER — Former Patriots tight end Aaron Hernandez is scheduled to appear Friday at 2:30 p.m. for a motion hearing in Fall River Superior Court.

The prosecution and Hernandez's lawyers are expected to argue over their respective versions of a gag order and prosecutors' request that they be given copies of Hernandez's visitor logs and phone call recordings at the Bristol County House of Correction in Dartmouth.

Prosecutors said that Hernandez, 24, discussed the June 2013 murder of Odin Lloyd in "coded messages," and that he made references to his and his co-defendants' alleged criminal liability in the case, according to court records.

Hernandez's lawyers have called the prosecution's request for the jail records and phone calls a "fishing expedition."

Meanwhile, Hernandez's lawyers are also expected to press their case for a new gag order that they said is needed to prevent law enforcement authorities from leaking prejudicial information about the case to the news media. Hernandez's lawyers want prosecutors and police detectives to swear an oath that they have never and will not issue prejudicial statements to the public.

Prosecutors said they have not violated a previous court order banning prejudicial information from being leaked to the public. The prosecution said Hernandez's defense team has made baseless claims of misconduct in an attempt to lay the groundwork for future legal claims, including an appeal.

Hernandez is being held without bail at the county jail in Dartmouth. He is charged with murder and firearms violations stemming from Lloyd's killing in the North Attleborough Industrial Park. Police said Lloyd was shot five times with a .45-caliber handgun. Hernandez last appeared in court on Dec. 23.

Meanwhile, court records indicate Hernandez's cousin, Tanya Singleton, who is charged with conspiracy to commit accessory after the fact and criminal contempt, has a motion hearing Friday at 3 p.m. in Fall River Superior Court. On Monday, Judge E. Susan Garsh granted a temporary order that Singleton's address not be released to the public out of concerns for her privacy and safety. Singleton is free on $15,000 cash bail.
